What goes into the veggie burger?
This veggie burger has got it going on! When I say “loaded” with veggies, I mean it! To make this deliciously flavorful and healthy veggie burger recipe, you will need:
- Olive oil, for cooking the broccoli and mushrooms.
- 8 oz Baby Bella Mushrooms, chopped into small bite size pieces (by hand, or in the food processor).
- 1 small head of broccoli. We’ll use the whole thing, with finely chopped/processed stems, and whole floret pieces. No waste!
- A small carrot, grated.
- A small zucchini, grated and drained.
- A few thinly sliced scallions.
- A can of chickpeas, and a can of black beans.
- Low sodium Worcestershire sauce, or vegan Worcestershire.
- Some good quality, preferably organic Miso paste.
- Some fresh garlic.
- Salt and pepper.
- Smoked paprika.
- Plain panko breadcrumbs.
- Egg Replacer, such as Bob’s Red Mill.
It’s all about the texture: prepping the ingredients.
Cooking down the broccoli and mushrooms
This veggie burger recipe does require some prep prior to forming the burger mixture and cooking, but trust me- it’s worth the wait. To make these vegan black bean and chickpea burgers, you will need to cook down the broccoli stems and mushrooms in some olive oil, then (briefly) the broccoli floret pieces. This keep the moisture content in check, and helps build flavor and texture.
Baking/drying the black beans and chickpeas
While you cook down those ingredients on the stove, you’ll also bake your drained and rinsed chickpeas and black beans in an even layer on a baking sheet. The beans will bake for 30 minutes. The baking also helps reduce the moisture content of the burger. While the burgers will still be moist, flavorful and delicious- these steps are key in making sure the burgers hold together well, and have a pleasant texture and mouth-feel.
A vegan black bean and chickpea burger with bite
Once you’ve got your broccoli and mushrooms cooked down and your beans dried, you’re ready to get the burger mixture assembled. Allow the beans to cool briefly, then pulse them in the food processor until they are roughly ground. You want them broken up, but you also want them to retain some shape/texture. Whole chunks are OK/encouraged.
Mixing it all up
Once your beans are roughly ground, add them to a bowl with your shredded carrots, shredded and drained zucchini, cooked broccoli and mushrooms, raw scallions, garlic, miso paste, panko breadcrumbs, smoked paprika, vegan Worcestershire, and prepared egg replacer. Mix well.
For best results, stick em in the fridge
After the burgers are mixed up, the mixture is still a bit warm. For best results- transfer the mixture to the fridge for 1-2 hours prior to forming the patties and cooking. Burger mixture can be made 1-2 days ahead of cooking.
Can the Miso Mayonaise be made vegan?
The delicious, umami-packed may sauce for these burgers can be made with regular or vegan mayonaise as the base! To make the Miso Mayo, you will need:
- Mayonaise or Vegan Mayonaise
- Fresh, crushed or pressed garlic
- Apple Cider Vinegar
- Good quality Miso paste
To make the sauce, simply whisk the above ingredients well until fully incorporated. In my experience, vegan mayo can have a bit more acidity than regular mayonaise, so I usually use a lighter hand with the apple cider vinegar when preparing the vegan version of the sauce. Both versions can be made ahead, and can be stored in the refrigerator for up to one week!
Does this veggie burger recipe freeze well?
If stored properly, this veggie burger recipe freezes very well! Just be sure to form the patties prior to freezing, and store in an airtight freezer bag. When you’re ready to cook the burgers, you can cook them right from the freezer! Just keep the heat medium-low, and add a few minutes to the cooking time for each side. The burgers will take about 5-7 minutes a side from frozen. Since they have a longer cooking time then when they are fresh, you want to be sure to keep the temperature down so they don’t burn.
What should I serve on the burgers?
Obviously, you should serve these burgers with the quick and easy Miso Mayo. Aside from that, the possibilities are endless! Here are some of my favorite toppings for the burgers:
- Thinly sliced red onion
- Shredded romaine lettuce or Boston Bibb
- Fresh sliced tomato
- Crisp dill pickle slices
- Melty sliced cheese, or vegan cheese
- Crisp coleslaw
Can I make them into full size patties instead of sliders?
This recipe yields 16 slider sized burgers, or 8 full sized patties! When forming the burgers, forget everything you know about making beef burgers, and pack them very firmly to make sure they stay together while cooking in the pan!
